1. The activated carbon filter removes harmful substances

Activated carbon removes harmful chemical components from water by adsorption. This is possible due to the enormous surface varying between 300 and 2000m² per gram which e.g. equals the size of a soccer field per 2 grams. The clue to that surface is a sponge like structure with pores of the size in the nanometer range. The material can be made out of numerous organic or mineral resources; usually hard coal or coconut shell. Activated carbon works very effectively towards non polar solvable substances, such as organic pollutants or micro pollutants. On a molecular level some parts of a substance when close enough to the coal surface will be adsorbed by Van der Waals forces enabling a weak chemical bond. As such when fully loaded activated carbon can be recycled and used again. Activated carbon treatment can be found in a variety of applications and areas and is also one of the most common treatments in the municipal water supply area. In combination with UV disinfection and as a side effect it optimizes the water quality for UV light to be used most effective making it a highly synergistic process combination.
